Abstract (en)
The invention refers to a combustor arrangement of a gas turbine engine or power plant, comprising at least one combustion chamber, at least one mixer arrangement for admixing air or gas to the hot gas flow leaving the combustion chamber. The mixer arrangement is adapted to guide combustion gases in a hot gas flow path extend-ing downstream of the combustion chamber, wherein the mixer comprises a plurality of injection pipes pointing inwards from the side walls of the mixer arrangement for admixing air portions to cool at least the hot gas flow leaving combustion chamber. The mixer arrangement (200) is applied to at least one volume of dilution air (129) flowing from a first plenum and at least one volume of cooling air (110) flowing from a second plenum.
